It only happens when I turn on the lights, no burning when I turn the key. I am so lost when it comes to electrical issues. I do not know what it is callled, but there is a electrical component that seems to be hooked to the dash lighting that is aluminum housing with a heat sink on it. 1st, what is this thing? and if I did not properly ground it when I put back the dash would it cause my issue?
